bined Plumb-Level and Guide-Line Holder, 1

of which the following is a specification.

The objects had in view in this invention are to provide a convenientand accurate instrument for brick-layers use to preserve a true cornerjoint, and consequently the laying of the bricks in level courses, whileit combines great facility and expedition in handling, resulting in moredurable and permanent work, every brick being leftin a good mortar-bedand not in a shattered and loose condition; and to these endstheinvention consists of a frame or upright having applied to it a seriesof angle castings or guides adapted to fit the corners of theprospective walls of a building, and which frame or upright is alsoprovided or armed with graduated plates, one at each of two sides, andwith line securing or holding slits or notches. The frame or uprightalso has applied to it clamps which effect a hold upon the bricks andpass through said frame or upright, their outer ends receiving keys orwedges which efiect the holding of the clamps in place and which areadapted to be readily withdrawn from said clamps. Applied to each sideof the frame or upright is a plumb-level or bob, as

also a spirit-level, all substantially as hereinafter more fully setforth, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view in elevation, showingmy brick-layers combined plumb-level and guide-line holder as appliedfor use. Fig. 2 is an enlarged plan view of the same, and Fig. 3 is ahorizontal section on the line a: a: of Fig. 1.

In the embodiment of my invention I employ an upright, A, which in thepresent instance consists of two boards or pieces, a a, joined togetherat right anglesto each other. The outer side of each board or piece Ctis provided with a plate, a, graduated in inches and fractions of inchesthroughout its entire length, while to the same sides of said boards orpieces are also applied, at suitable intervals apart along their length,guides or castings B B. The guides or castings are formed in pairs, theguides of each pair crossing each other at right angles, and oneextending from each of two adjacent faces or sides of the upright A, asshown, whereby the same is adapted for application to the corner of awall of abuilding or inclosure. The inner ends of the guides or castingsB are secured or bolted to the inner sides of the boards or pieces a aof the upright A at their inner the opposite corners of the wall beingput up.

Applied to the upright A, near its lower end and a short distance abovethe samesay a space apart equal to about four courses of bricksand tothe outer side of each board or piece a, a thereof, are clamps O C, forseouring the upright in position. Similarly applied to the upright A arealso addi-- M tional guides, B B The connection of the bottom guides, BB with the upright or frame A is effected by means of adjustingscrew-bolts and thumb-nuts 7) 19 respectively, the screw-boltsconnecting with the frame or upright A and passing through apertures inlateral extensions of the guides, while the thumb-nuts fit upon thescrew-bolts, as shown. This arrangement permits of the adjustment of theguides to the bricks, so as to allow for any little irregularities upontheir surfaces in plumbing the instrument. The inner ends of the clampsO O are passed through apertures in the boards or pieces a a, of the upright A and project therefrom, and are provided with apertures or eyes 0c, which receive keys or wedges of c, to effect the holding of the samein position. The outer ends of the clamps are extended at right anglesto their main or body portions, and are thus adapted to enter the greenmortar of the coincident joints of the wall and be clamped therein asthe wedges or keys 0 c are inserted and driven home in the aperturedends of said clamps. The keys or wedges c c are suspended by cords orwires 0 c connecting with the upper end of the upright A in any suitmentthe keys or wedges may be readily withdrawn or removed from the clampsby pulling or drawing upon the cords orwires at the top or upper end ofthe uprightt'. 6., after the putting up of the wall to that height bythe workman from the inside-it then, of course, being required toshiftthe implement, thus permitting of the ready manipulation of theimplement, so as to allow of the displacement of the same and itselevation to a higher point as the wall advances in height.

D D are plumb bobs or levels, one disposed upon each outer side of theupright A, as shown. Upon each outer side of the upright A is alsoprovided a spirit-level, E, for use in event the plumb bobs or levelsare incapable of use, as in windy weather.

From what has been disclosed the use of this invention is apparent. Itis only necessary to remark, possibly, that with two uprights, A,applied to the base of each of the opposite corners of the prospectivewall, and the required connection between the wall and the clampseffected in the manner as shown and as partly above described, the keysor wedges are inserted in the apertured projecting ends of said clamps,which will secure the uprights in position. The guideline is nowstretched, being inserted at its ends into the required slits or notchesb b of the uprights, and the implement is now ready for the laying ofthe bricks in the re quired courses, the uprights with their guides,with the aid of the plumb-bob or spirit-level, always preserving thecorner bricks plumb and level, together with that of the laying of theintermediate courses.

Having thus fully described my invention, whatIclaim, and desire tosecure by Letters Patent, is-

1. The combined plumb-level and guideline holder consisting of an angleupright provided with a series of angle castings or guides to fit theangle or corner of a wall and with clamps detachably connected therewithto engage with or enter the joints between the bricks of the wall,substantially as and for the purpose set forth.

2. The combined plumb-level and guideline holder provided with angleguides or castings adapted to fit the implement to the angle or cornerof a wall, the bottom guides being adjustable, substantially as setforth.

3. The combined plumb-level and guideline holder having a graduatedupright provided with the guide-line slits or notches, angle castings orguides to fit the angle or corner of a wall, and clamps to engage withor enter the joints between the bricks of the wall and confined to theupright by keys or wedges, substantially as and for the purposespecified.

4. The combined plumb-level and uideline holder having an uprightprovided with angle castings or guides to fit the angle or corner of awall, clamps to engage with or enter the joints between the bricks ofthe wall, and keys or wedges suspended from the top or upper end of theupright and engaging with apertures in the inner ends of the clamps,substantially as and for the purpose specified.

5. The combined plumb-level and guideline holder consisting of thegraduated upright having a series of guide-line slits or notches, theangle castings or crossing-guides applied to the upright and adapted tofit the corner or angle of awall, the clamps to engage with or enter thejoints between the bricks of the wall and provided at their inner endswith apertures, the keys or wedges engaging with the apertures of theclamps, and the suspending cords or wires of the keys or wedgesconnected or applied to the top or upper end of the upright,substantially as set forth.
